摘　　要：运用三段制、五段制井深轨道设计差异研究和层段井网校正等方法,发现侏罗系油藏井网不完善区域面积1.31 km^(2),部署油水井17口,调整井网5井次,可建产能1.8万t。采用声波变密度固井质量筛查和开发效果统计对比等方法,研究固井质量对侏罗系油藏开发效果的影响,发现固井补救虽能有效缓解固井质量差的问题,但整体油藏产能仅能发挥76%左右。By using the methods of difference research on deep trajectory design and interval well pattern correction of three-stage and five-stage well pattern, it was found that the well pattern of Jurassic reservoir was not perfect, with an area of 1.31 km^(2), 17 oil-water wells were deployed, 5 well patterns were adjusted, and 18 kt production capacity was built. By means of acoustic variable density cementing quality screening and development effect statistical comparison, the influence of cementing quality on the development effect of Jurassic reservoir was studied. It was found that cementing recovery could effectively alleviate the problem of poor cementing quality, but the overall reservoir productivity could only play about 76%.
